	* These are the commands understood by nfsctl().
       #define NFSCTL_SVC	       0       /* This is a server process. */
       #define NFSCTL_ADDCLIENT        1       /* Add an NFS client. */
       #define NFSCTL_DELCLIENT        2       /* Remove an NFS client. */
       #define NFSCTL_EXPORT	       3       /* export a file system. */
       #define NFSCTL_UNEXPORT	       4       /* unexport a file system. */
       #define NFSCTL_UGIDUPDATE       5       /* update a client's uid/gid map. */
       #define NFSCTL_GETFH	       6       /* get an fh (used by mountd) */

       struct nfsctl_arg {
	       int		       ca_version;     /* safeguard */
	       union {
		       struct nfsctl_svc       u_svc;
		       struct nfsctl_client    u_client;
		       struct nfsctl_export    u_export;
		       struct nfsctl_uidmap    u_umap;
		       struct nfsctl_fhparm    u_getfh;
		       unsigned int	       u_debug;
	       } u;

       union nfsctl_res {
	       struct knfs_fh	       cr_getfh;
